Answer:
The American Indian Movement is a Native American organization that has existed since 1968. The AIM is primarily recruited from activists outside of the classic reservations and is an indigenous movement that works against corruption and abuse of power by the official Indian reservation leaderships as well as for a revision of the American Indian policy.
Between the end of the 1960s and the mid-1970s, AIM made headlines due to spectacular, including some militant, resistance actions such as the occupation of Wounded Knee in 1973 and attracted the attention of the international public.
